In theory it's easy for any reader who wants to parse trailers to do so. But there are a lot of subtle corner cases around what counts as a trailer, when the trailer block begins and ends, etc. Since interpret-trailers already has our parsing logic, let's let callers ask it to just output the trailers. They still have to parse the "key: value" lines, but at least they can ignore all of the other corner cases. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
